BOBBIN-I-IOLDER.

Specification of Letters Patent.

Application filed February 1, 1915. Serial No. 5,562.

To aZZ whom it may concern:

Be it known that I, HowARD D. CoLMAN, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Bobbin-Holders, of whichthe following is a specification.

This-invention relates to devices for holding yarn masses, as for example bobbins; of warp yarn; and one of the objects of the invention is to provide holders which may be conveniently operated to discharge the bobbins.

The invention'has special, although not exclusive, reference to bobbin-holders adapted for use in automatic winders, a particular object being to provide bobbin-holders which may be operated by mechanical means to discharge the bobbins.

In the accompanying drawings, Figure 1 is a fragmental view of an automatic winder provided with bobbin-holders embodying the featuresv of this invention. Fig. 2 is a front view of the bobbin-holders looking in the direction of the axis of the bobbins. Fig. 3 is a sectional view taken in the plane of dotted line 8 of Fig. 1. Figs. 4 and ,5 are views taken in the planes of dotted lines 4 and 55, respectively, of Fig. 1. Fig. 6 is a fragmental view, on a reduced scale, showing the winding mechanism.

.In Patent No. 1,175,710, March 14, 1916, I have disclosed an automatic winder comprising a plurality of winder units, each unit comprising means for supporting and rotating a cheese, and two bobbin-holders, one located above the other. One of the bobbin-holders supports the bobbin being unwound, and the other bobbin-holder supports a reserve bobbin. The spent bobbin is withdrawn by the operative and a new or reserve bobbin substituted'therefor. The bobbin-holders thus alternate in supporting the reserve bobbin. To save labor, it'is desirable to provide automaticmeans for discharging the spent bobbin. In order that such mechanism maybe as simple as 'possible, itisdesirable that the spent bobbin be always in a particular one of the pair of bobbin-holders. It also is desirable that the reserve bobbin be placed in a particular one of the pair of bobbin-holders, in order that the operative shall not need tocon-. sider in which holder to place the bobbin,

and may thus acquire speed in the performance of the bobbin-supplying operation. I, therefore, have. provided above the bobbinholder a support into which the reserve holder, and for discharging the reserve bobbin from said support to the bobbinholder.

In Fig. 6 is indicated one formvof winding mechanism that may be used. A is the yarn mass being formed and B is a device for rotating said yarn mass and for traversing the yarn. C is a clamp to hold the end of the thread of the reserve bobbin. parts may be similar to those shown in my said application Serial No. 628,474.

For convenience in manufacturing'and assembling the winder, the winder units may be grouped to form a plurality of bays. The pairs of bobbin-supporting devices of each bay may have a common supporting framework which may comprise a front angle plate 1 and a rear plate 2 rigidly connected together by a suitable number of braces 3. Fixed to the angle plate 1 is a series of These brackets 4, one for each pair of bobbin-supporting devices. The supporting frame formed by the parts 1, 2, 3 and 4 may be attached to the framework of the winder in any suitable way; for example, certain of the brackets 4 may be secured, as at 5, to the brackets 6 that support the reserve threadend clamps C; and upon the rear side of the plate 2 may be secured pairs of lugs 7 and 8, each pair adapted to receive a hanger 9 arranged to be supported upon one of the V longitudinal beams v1O of the winder framework. The lug 7 rests upon anut 11 turned on the lower end of the hanger 9, whereby the position of the group of bobbin-supportingdevices may be properly adjusted at the I position shown in Fig. 3. As shown in Fig.

. termining the normal position of the pocket.

' displacement of the bobbin when the pocket The strip 16 also serves to prevent lateral 13 is swung upwardly.

A plate 17 extends lengthwise of the plate 2 behind the pockets 13, the plate 17 being spaced from the plate 2 by a bar 18. The rear end of the strip 16 is fixed to the plate 17. At the side of the pocket opposite to the strip 16 is a strip 19, the rear end of which is secured to the plate 17. The rear portion of the strip 19 is bent as at 20 to guide the butt end of the bobbin toward the left-hand side of the pocket and thus assist to keep the reserve bobbin away from the 1 runnin thread as will a Deal more full its hereinafter. If desired, the strips 16 and 19 may be integral at their forward ends and may be bent to form guides 21 to facilitate the insertion of the reserve bobbins.

Rigid with the forward end of the pivot 15 is a crank-arm 22 which extends into the path of movement of an inclined or cam member a on the traveling mechanism (not shown) of the winder. hen said cam member reaches the crank-arm 22 of a unit, the arm is raised to withdraw the pocket 13 from beneath the reserve bobbin, thereby discharging said bobbin laterally into the bobbin-holder for the active bobbin, the spent bobbin having previously been discharged from the active bobbin-holder.

The active bobbin-holder 23 may be of any suitable construction, that herein shown being generally similar to the bobbin-holder shown in Patent No. 1,045,879, dated December 3, 1912. In the present construction the active bobbin-holder comprises two parallel rods or wires2, the forward portions of said rods being fixed to a pivot 25. The ends of the pivot 25' rest in bearing sockets 26 in adjacent brackets 4. The wires 2 1 support a loop or pocket 27 of flexible material having a smooth inner side, as for example, muslin coated with oxidized linseed oil. The

, normalposition of the wires 2 1 and the loop 27 is determined by contact of the rear ends of the wires 24: with the lower flange of the plate 17, the wires being yieldingly held in such position by means of a tension spring 28 connected at one end to the forward end of one of the wires 2 1 and at its other end to a suitable fixed point. Any suitable means may be used to provide a back stop for the bobbin; herein is shown a hardenedmetal wear-plate 29 detachably secured to the plate 2.v In the present embodiment of the invention, the entrance ofthe bobbinholder is the open upper side thereof. The

projecting forward end 2 1 of one of the wires 24 constitutes a lever arm lying in the path of an inclined or cam member Z) of the traveling mechanism hereinbefore referred to. When the cam member 22 engages the arm 24, the loop 27 is tilted downwardly and rearwardly, whereupon the spent bobbin slides longitudinally out of the loop. Preferably a conveyer 30 is provided below the bobbin-holders to carry the empty bobbins to any desired point.

31 and 32 are guide plates to assist in directing the bobbins to the conveyer 30.

The bobbin-support 12 and the bobbin holder 23 are inclined so as to support the bobbins at right angles to the average direction of the running thread. As indicated in Fig. 1, the plate 17 spaces the reserve bobbin away from the wall 2, and thereforewhen the reserve bobbin is discharged into the bobbin-holder 23, the bobbin drops approximately vertically. A

By reference to Figs. 2 and 3, it will be space between the strip 19 and the edge 13 y of the pocket 13 for the passage of the running thread. The concave form of the pocket 13 keeps the reserve bobbin out of contact. with the thread.

33 is a stationary curved guard plate covering the pivot 25 at the entrance tothe reserve bobbin-support.

34: is a conveyer running along the front side of the row of bobbin-holders, for carrying full bobbins within convenient reach of the operatives.

Assuming that there is a reserve bobbin in the bobbin-support 12, the end of the thread on said bobbin being held in the reserve threa'd-end clamp C, and that a bobbin in the bobbin-holder 23 is being unwound, the operation is as follows: At the proper time in the operation of the winder, usually shortly after the bobbin in the bobbinholder 23 has been substantially or wholly unwound, the traveling mechanism reaches the unit, and the cam member I) tilts the loop 27 downwardly, thus discharging the exhausted bobbin onto the conveyer 30. As soon as the cam b has passed the arm 24, the spring 28 restores the loop 27 to its normal position. The end of the reserve thread having been tied to the exhausted thread, the cam a reaches the crank arm 22, and swings the pocket 13 up wardly,'thereby discharging the reservebobbin into the bobbin-holder 23. The fall of the yarn, places the bobbin in the bobbinsupport 12, and inserts the end of the yarn in the reserve thread-end clamp. 7

It will be noted that the bobbin is inserted into the active bobbin-holder 23 from above, thus removing the possibility of damage to the loop 27 through careless insertion of the bobbin through the front end of the loop :27, as in the bobbin-holder shown'in the patent hereinbefore mentioned.

It will be noted that theplate 1 extends in front of the forward end of the loop 27, thus preventing the bobbin from jumping out of the pocket during the unwinding operation.

I would have it understood that the invention is not limited to the details and ar- 7 rangement of parts herein shown, as various side-delivery bobbin-holder adapted to rotatably support a warp bobbin while being unwound, said bobbin-holder having an open upper side, and a bobbin-support pivotally suspended above the bobbinholder upon an axis extending adjacent to the vertical plane of the axis of a bobbin lying on the support, the latter being arranged to swing out of supporting position to allow the bobbin to fall through the open upper side of the bobbin-holder.
